Fig. 5.

Karyotypic composition of progenies of bona fide euploidy-descendants (being derived from one or more euploid parental individuals, as indicated by the number of branches) at each of the nine successive organismal generations (from S4 to S12). The six different colored circles represent six distinct karyotypic groups, numbers in the circles denote individual numbers within a given karyotypic group. Frequencies (%) of euploidy and proportions of SCV versus NCV were calculated and indicated at each generation (blue boxes). The bona fide euploid individuals at the S6 generation of this pedigree (marked by an asterisk in red) were used for meiosis study.
